Synopsis

Description

The euclen() function returns the length in bytes of the Extended Unix Code (EUC) character pointed to by s, including single-shift characters, if present.

The euccol() function returns the screen column width of the EUC character pointed to by s.

The eucscol() function returns the screen column width of the EUC string pointed to by str.

For the euclen() and euccol(), functions, s points to the first byte of the character. This byte is examined to determine its codeset.
The character type table for the current locale is used for codeset byte length and display width information.

Usage

These functions will work only with EUC locales.

These functions can be used safely in multithreaded applications, as long as setlocale(3C)
is not called to change the locale.
